Loudoun Water Civil Engineering & Surveying BOA
Loudoun County, Virginia
AMT provided civil engineering and surveying services to Loudoun Water for water and sewer related projects under a basic ordering agreement. The services requested under this contract include engineering, permitting, wetland and environmental assessments, surveying, land use entitlement services, geographic information systems, preparation of sites plans for new sewer and water related facilities, sewer and water line (analysis, design, and rehabilitation), and subsurface utility services. Task orders included:
Over the course of the two contracts, AMT has performed over 500 task orders for a total of 983,966 LF of main water line, 645,805 LF of main sewer line, and 46,225 LF of reclaimed water for a total of approximately 317 miles of utility as-builts.
AMT is currently providing surveying and GIS services to Loudoun Water: Our services include as-built survey of newly constructed water, reclaimed water and wastewater appurtenances (horizontal and vertical); preparation of ‘Record’ as-built survey drawing; conversion of survey data into GIS data format; and the population of a GIS geodatabase as a final deliverable. All GIS work is performed using ESRI ArcGIS 10 software.
36-inch Water Main (Route 7 Ashburn Village Blvd to Route 607): AMT prepared 60% design plans for approximately 3,000 ft of 36-inch high pressure water transmission main along Harry Byrd Highway (Route 7) from Loudoun County Parkway to Ashburn Village Boulevard. Plans included horizontal and vertical alignment of the water main, construction details including a trenchless crossing of Route 7, erosion/sediment control plan and details, and maintenance of traffic plans.
Goose Creek Properties: This task included preparation of a certified ALTA/ACSM Land Title Survey for 12 parcels of land being acquired by Loudoun Water from the City of Fairfax. The parcels were divided into a North area and South area with the total boundary consisting of 818 acres.
30-inch Water Main Willard Road (Route 639) to Loudoun County Parkway (Route 606): Task consisted of the preparation of 60% design plans for approximately 2,960 ft of 36-inch high pressure transmission water main. Plans included horizontal and vertical alignment of the water main, construction details including thrust restraints and a trenchless crossing or Loudoun County Parkway, erosion/sediment control plan and details and maintenance of traffic plans. In addition, AMT obtained a Nationwide Permit #12 for Utility Line Activities from the United States Army Corps of Engineers (USACE) and worked with the Metropolitan Washington Airports Authority (MWAA) allowing the project to obtain an expedited review and approval through MWAA rather than the more detailed review normally required under the provisions of the National Environmental Policy Act (NEPA).
